SELF-FILLING FOUNTAIN-PEN.

Specification of Letters Patent. Patented Nov, 11,1919,

Application filed May 17, 1919. -Seri2i1 No. 297,313. 7

the city of New York, county and State of New York, have discovered a new and industrially-useful Self-Filling Fountain- Pen, of which the following is a specification.

My invention relates to fountain-pen fillers of the type which constitute an elastic ink sack adapted to substantially fill the barrel of the pen, and means for compressing the sack to expel the air before the nib end of the pen is inserted into the ink. In fillers of this type pressingmeans are utilized'which include apresser bar lying within the barrel and adapted to be moved against the sack by means which are accessible from the outside of the barrel.

In pens of this type it is necessary to provide means for preventing the presser 'bar from moving longitudinally within the barrel when the same is moved to and from the sack, and this feature forms the subject of my invention and is characterized by the provision of a slide interposed between the presser bar and the operating lever and which slide also forms the necessary connection between the presser bar and the operating lever. 'Y

7 An illustrative embodiment of my invention is shown in the accompanying drawings in which Figure 1 is a longitudinal sectional view of a fragment of the barrel of a fountainpen equipped with a device embodying my invention, the parts being shown in position when emptying or filling the elastic sack.

Fig. 2 is a similar section showing the operating parts in normal or rest position.

Fig. 3 isa cross-section on line 3-3 Fig. 1.

Fig. 4 is a top plan View of bar, and

Fig. 5 is a perspective View of the slide.

Referring to the drawings in which the reference numbers indicate the same or'corresponding parts in all the figures, and wherein 6 is the barrel which accommodates an elastic sack 7. The barrel 6. has an elongated slot 8 which is adapted to house the presser the operating lever 9. The lever 9 is pivotally mounted between the ends by means of a yieldingring 1O housed within an inner annular groove 11 formed in the barrel.

The lever when moved into the slot 8- is re- I tained-bv a yielding catch12'dispo'sed to engage the notch 13 in the lever.

The lever 9 is connected pivotally to the rising lug 14 of a slide 15. The lug 14 pro- [jects through an elongated slot 16 of the presser bar 17. The presser bar has a raised portion 18 to house the slide 15 therein so that the same does not come in contact with the sack. The slot 16 is sufficiently long to allow the lug 14 to move therein when the presser bar is raised or lowered'by the movement of the lever 9. The end of the lever 9 is rounded so as to bear against the presser bar as will be seen from Figs. 1, 2 and 3, thereby preventing the lug 14 from moving up and down within the slot 16 when the presser bar is actuated. Y

It will 'be noted that the connection between the lever slide and presser bar is such that whenever pressure is to be applied to the sack, the work is done directly by the lever acting againstthe presser bar, as will be seen from Figs. 1 and 3. The slide prevents the lever from carrying the presser bar therewith and it supplies pressure to the presser bar. The lever 9 is of channeled shape to accommodate the lug 14 0f the slide and thereby reduce the clearance between the presser bar and the lever when the same are in collapsed or rest position.

I claim:

1. In a self-filling fountain-pen a presser bar, "an Operating lever and a member mounted to slide in the presser bar longitudinally of the bar and connected pivotally; to the lever.

2. In a self-filling fountain-pen a presser bar having an elongated slot, a slide having a lug projecting through the slot and adapted to move longitudinally of the presser bar and an operating lever connected pivotally to the lug.

14:. In a self-filling fountain-pen a presser her, an Operating lever pivotally mounted between its ends, and a member slidably mounted in the presser bar and pivotally connected to one end of the lever.

5. In a self-filling fountain-pen barreha member pivotally connected to the lever and mounted to slide in the presser bar 6. In a self-filling fountain-pen a presser bar having a raised portion between the ends, said presser bar having an elongated slot in said raised portion, a member I I I memes adapted to be located in the raised portion of the resser bar, said member having a lugv projecting through the slot so that the said member is free to slide relatively to the presser bar, and an operating lever pivot- .ally mounted between the ends and having one of its ends pivotally connected to the lug of the member.
